Device for keeping heating wires in position in a horizontal oven

Abstract

Device for keeping a heating wire ( 2 ) in position in a horizontal oven includes a ceramic bar ( 3 ) and a number of ceramic spacer elements ( 4 ). Each spacer element consists of a bar-shaped part, on which a Y-shaped part ( 6 ) is placed near the center of the bar-shaped part. The V-shaped part of the Y-shaped part can partially enclose the bar. Near one end, the bar-shaped part is preferably provided with a transverse part, which is at right angles to the bar-shaped part and runs parallel to the Y-shaped part, so that a U-shaped recess is created which can accommodate the heating wire and the other side of the Y-shaped part and the bar-shaped part together form an L-shaped recess in which the heating wire can also be accommodated. The one end of each spacer element is provided with a projection and the other end with a recess.

1. Device for keeping a heating wire in position in a horizontal oven, the device comprising:
 a bar and 
 a number of spacer elements, each spacer element consisting of a bar-shaped part, on which a Y-shaped part is placed near the centre of the bar-shaped part, the plane through the Y-shaped part being at right angles to the axial direction of the bar-shaped part, 
 wherein a V-shaped part of the Y-shaped part can partially enclose the bar, 
 wherein the bar-shaped part, near one of its axial ends, is provided with an upstanding transverse part which runs parallel to at the one side of the Y-shaped part, creating a U-shaped recess in which the heating wire can be accommodated, 
 wherein the other side of the Y-shaped part and the adjacent portion of bar-shaped part together form an L-shaped recess in which the heating wire can also be accommodated, and 
 wherein the spacer elements are made of ceramic material. 
 
   
   
     2. Device according to  claim 1 , wherein one end of the bar-shaped part of the spacer element is provided with a projection in line with the bar-shaped part and a recess is provided in a second opposed end of the bar-shaped part, so that the projection of the bar-shaped part of a first spacer element can interact with the recess of the bar-shaped part of a second spacer element when the first spacer element is placed against the second spacer element. 
   
   
     3. Device according to  claim 1 , wherein the length of the transverse part corresponds to a length of a stem of the Y-shaped part. 
   
   
     4. Device according to  claim 1 , wherein the V-shaped part of the Y-shaped part has an O-shaped opening so that the V-shaped part can partially enclose the bar. 
   
   
     5. Device according to  claim 1 , wherein the bar is cylindrical. 
   
   
     6. Device according to  claim 1 , wherein the bar is hollow.
